Consider the series of CMOS inverters in Fig. 3a. The threshold voltages of the n-channel transistors are VTN = 0.8 V, and the threshold voltages of the p-channel transistors are VTN = -0.8 V. The conduction parameters are all equal. VTC for any of the CMOS inverter in Fig. 3a is depicted in Fig. 3b.
